APPARATUS non GENERATING GAS.

Application fi led August 21, 1920. Serial No. 404,988."

To all whom it may concern Be it known that I, SETH HArns, a citizen of the United States, residing at Cleveland. in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in and Relating to Apparatus for Generating Gas, of which the following is a specification.

This invention relates to an apparatus for generating gas or gases, more particularly tochemical apparatus for causing reactions between materials, such for example as a acid.

One object of the invention is to provide an apparatus of this character comprising a relatively few number of parts shaped and arranged for correlation whereby certain experiments and formulae may be readily and easily carried out.

Another object of the invention is to provide an apparatus of this character so constructed that certain of the materials may be repeatedly used, and others readily substituted. I I

I Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawing.

Referring to the drawing wherein, I have shown, and herein described, one form of apparatus embodying my invention:

Fig. 1 is a view, partly in elevation and partly in section, of an apparatus embodying my invention.

Fig. 2 is a longitudinal sectional view of the apparatus. I Fig. 3 is a horizontal section on the line 33of Fig. 2.

Fig. 4 is a section'on the line 44 of Fi 2.

Fig. 5 is a view in perspective of the outer V liquid-holding element of the apparatus.

Fig. 6 is a side elevation of the bell element of the apparatus.

Fig. 7 's a'perspective view of the closure for the lower, open, end of the bell.

Fig. 8 is a plan view of the supporting ring for holding the bell in proper position within the liquid-holding vessel.

In the drawing, 1 indicates a cylindrical member, closed at its lower end. The member 1 is arranged to hold any desired quantity of certain of the material or materials-preferably a liquid material or materialswhich is or are to be used in the generating ofv agas or gases. I have shown th s holder 1 as a graduate, whereby it may be conveniently used as such and as a piece of apparatus capable of .use in generating gas, as will be later set forth. The graduate is provided with the usual graduations or scale 1 on one side and also an indicating line 1 to indicate the quantity of material that is to be placed therein when it is used as a generator. The' upper or open end of the graduate 1 is inclineddownwardly from the pouring lip 1 to a point diametrically opposite the. lip, as shown at 1 the purpose of which inclined end will later be described.

2 indicates a bell arranged to hold other material or materials whichis or are to be used in the reaction; The bell 2 is construct- 7 ed so that it may telescope into the graduate 1 (see Figs. 1 and 2) to permit contact of the materials placed in it and the graduate 1.

3' indicates a device fitted to the lower open end of the bell and adapted toretain per formed of suitable chemical resisting ma erial, and frictionally engaging the inner walls of the bell 2. .At 3 the plug 3 is formed with a groove, through which the liquid in the graduate 1 passesor flows into the hell 2 when the latter is positioned in the graduate 1, asshown in Figs. 1 and The plug 3 may be pro-videdwith a plurality of grooves Zi -uniformly spaced around its side wall. 4 indicates a delivery tube connected to the upper end of the hell 2. i

The tube 4:" is pre erably formed integral with the walls of the bell 2- and' its upper end. may be bent downwardly to permit the 1 00 easy attachment of one end of, a flexible tube 5 without causing a kink in the'latter. The flexible tube 5'is preferably connected at its opposite end to one end ofa benttube 6,

the free open end of which is submerged in a hydraulic tank 7 so that the gas conducted by the tubes 5 and 6 from the hell 2 will rise into a receiver 8 which is inverted and supported on the shelf 7" in the tank 7.

9 indicates the means for connectingthe hell 2 to and supporting it within thegrad- 'uate or holder with its lower end sub- The material supporting 85 merged to the desired extent in the liquid material therein, as shown in Fig. 2. The connecting and supporting means 9 are preferably constructed in such manner that they support the hell 2 at the desired point or height, preventing it from descending downwardly, but permit it to move upwardly due to explosion 01 the gas, thus avoiding an explosion of the apparatus and resulting damage and injury. The connecting and supporting means 9 preferably comprise a clutch ring, which, by engagement with the inclined end -wall 1 of the holder 1, is caused to clamp the opposite sides of the hell 2 and thus support it in the holder 1. In orderxto insure a locking between the hell 2 and clutch ring, I prefer to roughen, in a Wellknown manner, the opposite sides of the bell 2, as shown at 10.

My invention is adapted for generating gas or gases for practical purposes and for conducting chemical experiments in a chemical laboratory. For these purposes a certain quantity of dry material B may be placed inside the hell 2 and the stopper or plug 3 applied to its lower end. The ex-' periment may then-be carried out. As soon as the reaction is completed the bell 2 may be raised above the material in the graduate, or itmay be removed from the holder 1 and its lower end submerged in water or other solution to wash the material B or carry out another reaction by the substitution of another. charged bell 2, the grooves 3? permitting the Water or solution to flow into the hell 2 into contact With the material therein. It will thus be seen that after the hell 2 charged with the desired materials, several chemical experiments can be carried out Without recharging the bell 2. Various ma terials may be used as desired for causing reactions, for example I may put a charge of zinc in the bell 2 and a charge of hydrochloric acid in the holder 1, and when the bell 2 is positioned therein, the hydrochloric acid will flow through the grooves 3 and permit the following reaction:

the hydrogen gas passing ofi through the tubes 4, 5 and 6 and being collected in the receiver 8. i

What I claim is:

1. In apparatus of the class described, the combination of a liquid holder open at its upper end, a bell telescopically fitting said h de a d arran to celled ga in its upper P rt on, an a d ta habl d vi closing the lower end of said bell and hold ing material therein, said device being formed with a groove through which the liquid in the holder may flow to permit re actions in said bell.

2. In apparatus ptthe class described, the combination of a graduate for liquid, a bell removably fitting intosaid graduate, and a plug removably fitting the lower end of said bell for closing it and holding material therein, said plug being formed 7 with an opening through which the liquid in said graduate may flow into said bell.

In apparatus of the classdescribed, the

combination of a holder'for liquid, a bell removably fitting into said holder andJarranged to coll ct gas in i uppe port on, detachable perforated means for closing the lower end of said bell, whereby material may be retained therein to permit reactions due to liquid flowing through the perfonation or s d c os ng me ns and mea s eng ging said bell and the upper end of said holder for supporting. said bell thereon, but permitting its movement upwardly. V

at. In apparatus of the class described, the

5. In apparatus of the class described, the combination of a graduate for liquid, the upper end of said graduate being, inclined from one side to the other, a bell arranged to telescope into said gradnate, periorated means for closing the lower end of said bell, whereby material may be retained therein to permit reactionsdue to liquid flowingi through the perforation of said closing means, and a clutch ring engagingthe upper inclined end of said graduate and the sides of said bell to support the latter in said graduate.

In testimony whereof I affix my signature. '1
